BS EN 1627:2011 BRITISH STANDARD National foreword This British Standard is the UK implementation of EN 1627:2011 It supersedes DD ENV 1627:1999, which is withdrawn BSI, as a member of CEN, is obliged publish EN 1627 as a British Standard However, attention is drawn to the fact that during the development of this European Standard, the UK committee voted against its approval as a European Standard The reason for this vote by the UK committee B/538, is due to concerns regarding to the scope of this standard does not address all known burglary methods or account for specific attacks upon lock products This standard does not provide a means of testing windows and doorsets with an intended use for Resistance classes and as specified in Table C.1 of this standard However they can be tested and assessed in accordance with BS 6375-3:2009 clause 5.13.2 in conjunction with the ‘UK Police Service (Secured by Design) Interpretation document for BS EN 1627, BS EN 1628, BS EN 1629 & BS EN 1630’ (compiled by the SBD Test House Studies Group) Manufacturers in the UK seeking classification for their window products to Resistance Class or above, or for their doorset products to Resistance Class or above, are drawn to the test and assessment requirements within BS EN 1627 in conjunction with the ‘UK Police Service (Secured by Design) Interpretation document for BS EN 1627, BS EN 1628, BS EN 1629 & BS EN 1630’ In addition, with doorsets, the lock and cylinder test requirements detailed within PAS 24:2012 (Annex A) further provides enhanced security performance guidance For window and doorset products the following minimum performance requirements are available: –– Windows can be tested and classified for Performance Characteristics detailed in BS 6375-2:2009 Clause and the classes detailed in table A.1 –– Doorsets can be tested and classified for Performance Characteristics detailed in BS 6375-2:2009 Clause and the performance requirements for Medium class in Table A.2 The UK

classes – Classification according to EN 1627 C.1 Introduction It has taken several years and many lively debates by the member states representatives to agree the method of classifying burglar resistance construction products according to ENV 1627 During these discussions the attack methods employed by the burglar (modus operandi) and crime statistics from National sources have been taken into consideration Also a series of development tests has been carried out and commonly available tools have been grouped into kits for use in the various classes detailed in this Standard The issue of reproducibility and repeatability of the manual attack test has been raised by a number of the member states To address these issues the overall assessment has been enhanced by the further development of the static load test, and the manual attack, now excluded from class The combination of the three test methods, static loading, dynamic loading and manual attack has given rise to an assessment procedure that is more robust and covers that relevant elements relative to each of the classes and therefore the anticipate burglar Observations in a number of the member states have concluded that the move from the more traditional level lock towards cylinder-operated locks resulted in an increase in the number of burglaries employing drill attacks on cylinders This, in turn, gave rise to a significant increase in the use of drill resistant cylinders with a consequence that the occurrences of drill-based attacks have all but disappeared It is this experience that has lead to the requirement for drill resistance cylinders according to EN 1303 and has allowed the creation of tool kits in the lower classes that not include drills The various classes detailed in this standard are intended to cover the opportunist or casual burglar as well as the more experience and professional Whilst this standard includes a number of classes the difference between each consecutive class varies The most significant step is that between classes and This reflects the two distinct groups of burglars recognised in this standard and is discussed in the following paragraphs C.2 Resistance classes to Classes 1, and are intended to address the levels of attack normal associated with the casual or opportunist burglar It is believed that these attacks are the result of an opportunity presenting itself with no particular regard to the likely reward that success may bring The level of force used in not excessive and the tools used are more likely to be common hand tools and levers Burglaries covered by these classes are likely to avoid noise and unnecessary risk As risk is associated with time, the period spent attempting to gain entry is limited and varies with the classes Likewise the level of resistance encountered during the attack is a factor High levels of resistance often resulting in aborted attack C.3 Resistance classes to Resistance classes 4, and are associated with the more experienced and professional type burglar with a more focused aim and knowledge of the likely reward that success may bring These attacks are general planned with knowledge of the construction products to be defeated Noise is not 23 BS EN 1627:2011 EN 1627:2011 (E) an issue and time is less of a concern The tools used often include powerful, single operator power tools with a high likelihood that organised crime is involved Table C.1 — Anticipated method and attempts to gaining entry Resistance class Anticipated method and attempts to gaining entry The casual burglar attempts to gain entry using small simple tools and physical violence e.g kicking, shoulder charging, lifting up, tearing out The burglar typically attempts to take advantage of opportunities, has no specific information on the level of resistance offered by the construction product and is concerned with both time and noise No specific knowledge of the likely rewards is anticipated and the level of risk the burglar is willing to take is low The casual burglar additionally attempts to gain entry using simple tools e.g screwdriver, pliers, wedge and in the case or grilles and exposed hinges the use of small handsaws Mechanical drilling tools are not associated with this level of burglar as a result of the use of drill resistant cylinders The burglar typically attempts to take advantage of opportunities, has little knowledge of the likely level of resistance and is concerned with both time and noise No specific knowledge of the likely rewards is anticipated and the level of risk the burglar is willing to take is low The burglar attempts to gain entry using a crow bar, an additional screwdriver and hand tools such as a small hammer, pin punches and a mechanical drilling tool With the use of the crow bar the burglar has the opportunity to apply increased forces With the drilling tool the burglar is able to attacked vulnerable locking devices The burglar typically attempts to take advantage of opportunities, has some knowledge of the likely level of resistance and is concerned with both time and noise No specific knowledge of the likely rewards is anticipated and level of risk the burglar is willing to take is medium The practised burglar uses in addition, a heavy hammer, axe, chisels and a portable battery powered drill The heavy hammer, axe and drill give the burglar an increased number of attack methods The burglar anticipates a reasonable reward and is likely to be resolute in his efforts to gain entry He is also less concerned with the level of noise he produces and is prepared to take a greater risk The experienced burglar uses in addition electric tools e.g drills, jig- and sabre saw, and an angle grinder with a disc of max 125 mm diameter The use of the angle grinder further expands the range of attack methods likely to be successful The burglar anticipates a reasonable reward, is resolute in his efforts to gain entry and is well organised He also has little concerned for the level of noise he generates and is prepared to take a high level of risk The experienced burglar uses in addition spalling hammer, powerful electric tools, e.g drills, jig- and sabre saw, and an angle grinder with a disc of max 230 mm diameter The tools are capable of being operated by a single person, have a high level of performance and are potentially very effective The burglar anticipates a good level of reward, is resolute in his efforts to gain entry and is very well organised He also has no concerned for the level of noise he generates and is prepared to take a high level of risk 24 BS EN 1627:2011 EN 1627:2011 (E) Annex D (normative) Field of application D.1 Dimensions The classification of a product is

elements shall be permissible for cylinders and protective hardware on construction products in resistance classes to without any expert statement by the testing laboratory, if the means of installation and the length of fixing lugs of the protective hardware remain unchanged, and if evidence exists of conformity with the requirements of Table The exchange of lock cylinders on construction products in resistance classes and is permissible without an expert statement only, if the burglar resistant characteristics of the construction products are not impaired This is the case, if the required protection of the lock cylinder by the protection shield (extended version), the cylinder with a cover or other measures have been taken into account during the test and have been recorded in the test report The exchange of floor and rebate seals is permissible in all classes if the burglar resistant characteristics of the construction products are not impaired
